Morphology | Morphometrics
Barbel with a single-based branch arising from stem; 4-6 lateral branches arising from medial branch, proximal pair from just distal to origin of medial branch; all branches with rounded, club-shaped tips; stem pigmented up to terminal bulb; bulb elongate, occupying most of distal barbel with slight constriction and internal pigment distally; a medial row of 8-10 prominent terminal filaments around distal tip and 1-3 pairs of small, lateral terminal filaments near ventral side of constriction in bulb (Ref. 45801).
Epi- and mesopelagic (Ref. 58302).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.80 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
